Nov. 26, 1963 INVENTOR. ABRAHAM GROSS/14AM rmgusr MIN" United StatesPatent 3,111,726 FIXED AND MOVABLE SASH WINDGW CONSTREJCTION AbrahamGrossman, 9339 Rhea St., Nortln'idge, Calif. Filed Sept. 23, 1960, Ser.N 583% 1 Claim. (Cl. 2tl-52) This invention relates to a windowconstruction incorporating a horizontally slidable inner sash and anouter sash which is fixed against movement with respect to said innersash. The teachings of the invention may be applied, if desired, to theconstruction of doors of a similar nature and it is not intended thatsaid teachings be limited specifically to the type of window disclosed.

However, as will be apparent to those skilled in the art, the teachingsof the invention are particularly applicable to windows and doorsconstructed from aluminum extrusions since the configurations in whichsaid extrusions may be designed greatly facilitate the application ofthe teachings of the invention to such windows. In prior art fixed andsliding sash horizontal window constructions, the installation of thefixed sash and the securement thereof against movement in the frame ofthe Window has entailed considerable hand work and the provision ofnumerous auxiliary parts or extrusions intended to integrate the fixedsash as a part of the window frame construction.

It is, therefore, an object of my invention to provide a horizontalwindow incorporating a horizontally slidable sash and a mating fixedsash which includes a perimetrical frame including a head and a sillmaintained in spaced relationship with each other by means of laterallyspaced jambs, the aforesaid sill incorporating inner track means adaptedto receive and support the sliding sash and the fixed sash being locatedin an outer channel in said head and said sill but being restrainedagainst movement in said channels by means of a tie post which isslidably movable into abutting relationship with the exposed stile ofthe fixed sash to restrain said fixed sash against movement with respectto said frame.

Another object of my invention is the provision of a window including aframe of the aforementioned character wherein the aforesaid head andsill have elongated receptacles communicating with the channels in saidhead and sill which, respectively, receive the upper and lower rails ofthe fixed sash whereby said elongated receptacles will serve as tracksand retention means for interlocking means connected to the oppositeextremities of said tie post which serves to restrain the fixed sashagainst movement in said frame.

Therefore, during the assembly of the window or door constructed inaccordance with the teachings of my invention, one jamb and theassociated head and sill may be joined in abutting relationship with oneanother, the fixed sash can then be slid into place in the outerchannels of said head and sill and the interlocking means on the tiepost inserted in the elongated receptacles communicating with saidchannels. The entire assembly of tie post and interlocking means canthen be slid through the channels into abutment with the adjacent stileof the fixed sash. Subsequently, the other jamb is attached to the freeends of the head and sill to define the window frame. The movable sashcan then be inserted in the frame in accordance with conventionalpractice.

After the tie post has been moved into abutting relationship with thestile of the fixed sash in the above described manner, the interlockingmeans is secured to adjacent portions of the head and sill to fixedlyretain the tie post against movement with respect to the frame of thewindow. Therefore, the tie post thus serves the dual fidlljifi PatentedNov. 26, 1963 "ice 2 function of preventing movement of the fixed sashand also of rigidifying the frame at its center by securing the head andsill rigidly to each other.

Other objects and advantages of my invention will be apparent from thefollowing specification and the accompanying drawing which is for thepurpose of illustration only and in which:

FIG. 1 is a front elevational view of a window constructed in accordancewith the teachings of my invention;

FIG. 2 is a transverse sectional view showing the relationship of thefixed and sliding sashes of said window;

P16. 3 is a vertical sectional view taken from the broken line 3-3 ofFIG. 1;

FIG. 4 is an enlarged fragmentary sectional view taken on the brokenline 44 of FIG. 3;

FIG. 5 is a vertical sectional view taken on the broken line 5--5 ofFIG. 4; and

FIG. 6 is an isometric view of a typical interlocking device utilized inconjunction with the tie post of the window of my invention.

Referring to the drawing and particularly to FIGS. 13 thereof, I show awindow 10 constructed in accordance with the teachings of my inventionand including a frame 12 which is constituted by a series of identicalaluminum extrusions serving the functions of a head l t, a sill l6 andjambs l8 and 29. Each length of extrusion 22 constituting the variousmembers of the frame 12 is characterized by the provision, as best shownin FIGS. 2-5 of the drawings, of an inner channel 28 having a track 26therein and of an outer channel 24, said inner channel having anelongated receptacle 30 in communication therewith.

Mounted for movement on the track 26 in the sill 16 is a sliding sash4%, said sash including stiles 42 and top and bottom rails 44 and 46,respectively, said stiles and rails encompassing a pane 48 of glass.Mounted in the lower rail 46 are rollers 52, one of which is shown inFIG. 3 of the drawings, said rollers engaging the track 26 located inthe inner channel 28 of the sill 16 to permit the sliding sash 4%) to bemoved on the track 26. A handle 54 secured to the right-hand stile 42,as viewed in FIG. 2 of the drawing, may be grasped to facilitatemovement of the sliding sash 40.

The right-hand stile 42 of the sliding sash 40 has interlocking means 58thereupon, as best shown in FIG. 2 of the drawings, for a purpose whichwill be described in greater detail below. Vertical Weatherstripping 62constituted by mohair filaments is mounted on each of the stiles 42 toseal the outer surfaces of said stiles against infiltration of air, dirtor moisture.

The fixed sash is fabricated from the same basic extrusion as thesliding sash 4t) and includes vertical stiles 72 and upper and lowerrails '74 and 76. However, the lower rail 76 of the sash 76 does notincorporate rollers similar to the rollers 52 incorporated in the lowerrail 46 of the sliding sash 40. As a matter of fact, the lower rail 76of the fixed sash 70 is superimposed on an inverted channel 78, shown inphantom in FIG. 3 of the drawing. Thus, the inverted channel '78 locatedin the outer channel 24 of the sill 16 maintains the rail 76 of thefixed sash 70 at the same level as the rail 46 is maintained byengagement of the rollers 52 upon the associated track 26.

It will also be noted that, as best shown in FIG. 2 of the drawing, achannel 78 is disposed in the righthand jarnb 20 of the frame 12 and theright-hand stile 72 of the fixed sash 7t) abuts thereupon. Thus, thelengths of channel 78 serve to locate the fixed sash 70 with respect tothe frame 12. It will be noted that the sash 70 incorporates a pane 82of glass.

Mounted at the left-hand stile 72 of the fixed sash 7'3 is a tie post9%), said tie post being constituted by an aluminum extrusion 92 which,as best shown in FIG. 2 of the drawing, includes an inner face d4 whoselower extremity overlies the chann l wall 95 and a transverse web $8adapted to span the outer channels 24- of the head 14 and sill 16 of theframe 12. It should be noted that, as best shown in FIG. 3 of thedrawing, the upper extremity of the inner face 94 of the tie post 90engages the underside of the channel wall 26 in the head 14 of the frame12.

A rib 192 is provided on the inner surface of the inner face 94 of theextrusion 92 constituting the tie post 9i) to define a receptacle forthe reception of a vertical Weatherstrip 194 on the left-hand stile '72of the fixed sash 76. The extrusion 92 also includes an outer face 165which overlies the left-hand stile 72 of the fixed sash 76.

The tie post 99 is, as best shown in FIGS. 2-6 of the drawing,maintained in operative relationship with the adjacent left-hand stile72 of the fixed sash 7i) and the outer channels 24 of the head 14 andsill 16 by interlocking and securement means generally indicated at 11%.The interlocking and securement means 110 is constituted by asubstantially T-shaped clip 112, said clip being fabricated from analuminum extrusion and including a head 11 i and a shank 116. When theclip 112 is inverted, the head 114 actually assumes the function of abase for the shank 116.

In any event, one of the interlocking and securement means 119constituted by the clip 112 is secured to each extremity of the tie post90 by means of a screw 118, or similar fastener, extending throughcorresponding openings in the shank 116 and the transverse web 98 of thetie post. The openings 120 and 122 in the shank 116 and the web 93,respectively, are pre-drilled and may be pro-threaded if desired. Inaddition, pre-drilled openings 126 are formed in the base or head 114 ofthe clip 112.

During the assembly of the component parts of the window it theright-hand jamb 2i and head and sill 14 and 16 are assembled inend-to-end relationship and the channels 78 inserted in the right-handjamb 20 and the outer channel 24 of the sill 16 in the manner shown inFIGS. 2 and 3 of the drawing, respectively. The fixed sash 70 is thenslid into the outer channels 24 of the head and sill until it abuts onthe vertically oriented filler channel '78 in the right-hand jarnb 20and is supported on the underlying filler channel 73 in the outerchannel 24 of the sill 16.

When such location of the fixed sash 70 with respect to theaforementioned frame members has been accomplished, the interlockingmeans 110 on the opposite extremities of the tie post 90 are inserted inthe elongated receptacles 30 communicating with the outer channels 24 inthe head and sill 14 and 15, respectively. The tie post 9b is thenpushed between the head and sill 14 and 16, respectively, until thetransverse web 98 thereof abuts on the left-hand stile 72 of the fixedsash 71). When this occurs one of the openings 126 in the head or base114 of the clip 112 is juxtaposed to a corresponding opening 128 in thebottom of the inner channel 28 immediately adjacent the track 26. Thisis true of both the upper and lower interlocking members 110 and isillustrated in FIGS. 4 and of the drawing.

Moreover, it is possible to eliminate the screws 130 and rely uponfrictional engagement of the bases 114 of the clips 112 with theadjacent walls of the receptacles 30. As a matter of fact, thefrictional engagement between the receptacles fail and the bases 114 ofthe clips 112 is frequently augmented by the slightly angularorientation of the bases 114 of the clips 112 with respect to thereceptacles 30.

When the openings 126 in the head or base 114 and 128 in the bottom ofthe channel 28 in the sill 16 and the similar openings in the head 14are juxtaposed, screws 1343 are driven into said openings to secure thehead or base 114 of the clip 112 against movement with respect to thehead 14 and sill 16 of the frame 12. In this manner the tie post 94serves as the sole restraining element for the fixed sash '79 and alsoacts as a structural beam integrating the head 14 with the sill 16.After the tie post 9% has been assembled in operative relationship withthe head and sill 14 and 16, respectively, the left-hand jamb 18 may beassembled with the as sociated extremities of said head and sill. Thesliding sash 40 can then be inserted into operative relationship withthe track 26 in the inner channel 28 of the sill 16.

It will be noted that, when the movable, sliding sash 40 is in closedrelationship with the opening defined by the frame 12, the stileinterlock 58 on the right-hand stile of the sliding sash 40, as bestshown in FIG. 2 of the drawing, will engage the inner side of the innerface 9-4 of the tie post 96 and the vertical Weatherstrip 62 thereu onwill engage the outer surface of said inner face to create a weatherseal therebetween. It will also be noted that the Weatherstrip 62 on theleft-hand stile 42 of the sliding sash 4t) engages the inner surface ofthe inner wall of the inner channel 28, as best shown in FIG. 2 of thedrawing, when the sash 40 is in closed position.

By providing a window incorporating a fixed sash which is retainedagainst movement by the simple expedient of a sliding tie post, Ieliminate the necessity for the extensive modifications of the framepreviously found in prior art constructions. In other words, by thesimple expedient of pre-drilling the holes in the bottoms of thechannels and in the base or head of the clips, I make it possible toreadily assemble the tie post in operative relationship with the silland head of the frame and with the exposed stile of the fixed sash.Therefore, the necessity for providing fastening clips and directconnections for the fixed sash to the frame of the window is eliminated.

Furthermore, the time which must be expended in assembling the window ofmy invention is much less than that entailed in the assembly of priorart window constructions and the inherent rigidity imparted to thewindow frame by the tie post materially enhances the structuralintegrity of the entire window construction of my invention.

I claim:

In a window construction, the combination of: a frame having a head andsill and upper and lower track means at the front of said head and sill,said head and sill having receptacles therein at the rear thereof andjambs supporting said head and sill in spaced relationship; a slidingsash supportd on said track means; a second sash supported on said headand sill; a tie post extending between said head and sill and engagingsaid second sash to prevent movement thereof; and interlocking meansconnected to the opposite extremities of said tie post for connectingsaid extremities to said head and sill, said interlocking means beingconstituted by clips each having a leg secured to an extremity of saidpost and a base longitudinally slidable and engaged in an associatedreceptacle of said head and sill, whereby frictional engagement of saidbase in an associated receptacle will prevent longitudinal, slidablemovement of said clip.
